The bite on that tooth may be too severe. This can be adjusted easily. It could be the root itself is defective. Calcium treatments usually correct this, but, if the root is broken, it may need to be extracted. This isn’t easy to determine, even with x-rays.
Teeth with root canals are not fully dead. So, long ago we designed a root canal therapy using calcium materials that enables the dentist to re-fill the root canals. The is an advantage over many root canals filled with materials that cannot be removed. Then the tooth has to be extracted. Root Canal THERAPY is a series of treatments until healing is complete, not a one shot deal.
